The Los Angeles City Council on Wednesday approved several new rules aimed at reducing the number of abandoned and poorly maintained vessels docked at the 17 marinas at the Port of Los Angeles.

So-called liveaboards will now be required to show proof of ownership and minimum liability insurance of $300,000, provide written authorization from the port’s marina operator and undergo annual boat inspections.

If a boat fails to meet state and federal requirements, owners will have 90 days to prove that it is seaworthy.

Last year, the port disposed of more than 130 derelict or abandoned vessels.
